Application March 15,

7 Claims.

My invention relates to wire-working tools, and particularly to a tool for splicing together the ends of wires.

An important object of my invention is to provide a tool of the character described which is simple and efficient and cheap to manufacture, and which can bev used by perso-ns unskilled and unpracticed in wire splicing to produce with little effort on the part of the operator, uniform splicings which form a strong and enduring connection between the wire-ends.

Other objects and advantages of my invention will be apparent from a reading of the following description in connection with the drawing, wherein for purposes of illustrtation I have shown a preferred embodiment of my invention.

In the drawing:-

Figure 1 is a perspective View of the embodiment showing the same in the condition in which it is .initially applied to a pair of wire-ends, which are shown in dotted lines, Y

Figure 2 is a perspective View showing the tool in use.

Figure 3 is aside elevational view bodiment.

Referring in detail to the drawing, wherein like numerals refer to like parts throughout the same, the numeral 5 refers generally to the elongated rectangular block which may be conveniently made of cast metal and of suitable cross-section.

Close to one side of the top ofthe block and eX- tending from one end thereof to a central point of the block in the wire-end receiving groove 6 whose inward end opens is a rounded or substantially semi-cylindrical recess 1 which opens through the said one side and top of the block. The bottom of the inner end portion of the groove 6 is angularly depressed asindicated at 6a in Figure 3.

Traversing the top of the block 5 approximately at the center thereof is a second wire receiving groove 8V of approximately the same depth and size as the groove IiY and opening at its ends through the opposite sides of the block. One end of the groove 8 opens as indicated at 9 into the recess I While the opposite end of the groove 8 opens as indicated at I8 through the apex of a triangular lateral extension II on the side of the block opposite the recess 1.

of the emrecess 'I on the side of the groove 8 opposite the position of the groove I5, and this forms the pivotal mounting for a swingable closure member designated I3 which is arranged to swing back and forth across the block.

A pivot such as a screw I2 is located near the I 1933, Serial N0. 660,918

The closure I3 comprises a flat rectangular metallic plate through one corner of which the screw pivot I2 passes. The plate is about the same width as the block 5 so that when it is swung into the closed position shown in Figure 2 it substantially coincides with the portion of the top of the block on which it is then superposed. The plate I3 has a triangular lateral extension I4 of the same size and dimensions as the lateral extension II of the block so that the portion I4 coincides with the extension II when the plate I3 is in its closed position. The free end of the plate has a portion severed as indicated at I5 and the separated portion turned upwardly and over to provide the handle I6. The edge I'Irof the plate is provided with a small rectangular notch I8 intermediate its ends, and between the notch and the pivot it is provided with a larger rectangular notch I9 of a width approximately equal to that of the recess 'I which it exposes, Vthese notches enabling seeing the length of wire left in the groove 6 and in the recess I during the splicing without disturbing the plate I3 from its closed position.

Y The wire-ends to be spliced are laid along the groove 8. in side by side manner. Then one of the wires is bent laterally with a pliers or any other suitable means and then placed into the groove 6 as indicated at 20 in Figure 1. The other wire 2l' is left in the groove 8. Then the closure plate I 3 is swung from the open position shown in Figure 1 to the closed position shown in Figure 2 in which it holds the wires 20, 2| in their respective grooves. Then a pliers or the like generally designated 22 is used to graspl and clamp the wire ends 23, 24 which are then extending from the recess I at points inward of their respective terminals, so that the wire portions 23, 24 are held in side by side relationship'as shown. Then the block 5 is rotated in one direction while the pliers 22 is held still, so as to wind or coil the Wire end 20 uponrthe wire end 2I. When this has been accomplished, the closure I3 is opened and the tool removed from the wires and then the wire end 24 is laid in the groove 6., and the wire end 23 in the groove 8. The tool being then in a position reversed with respect to the rst described position is then rotated until a second coil like that generally designated 25 in Figure 2 isrcompleted, whereupon the wire-ends will have been accurately, uniformally, strongly, and inseparably spliced. With this arrangement of the wire-ends, the stronger the pull upon the wires, the stronger the connection between the wire ends becomes. Y

It will be observed that the inner side of the groove 6 where it merges into the recess 1 is in substantially the same plane as the inner end of the recess 1, so that the wire moving from the groove 6 into the recess 1 moves into engagement With the said inner end of the recess. Supposing that a preceding convolution of the coil being made is in existence, such convolution will coact with the inner end of the recess in determining the formation of the next convolution, byV conning the portion of the wire in process of being formed into a succeeding convolution, into a certain form and curvature. 'Ihe curved Wall of the recess also assists this formation process. The result of the coactions just described is production of uniformly curved and spaced convolutions.

It will be obvious that linesmen, farmers, and other persons who are frequently called upon to splice wire-ends, will find that the device of the invention saves time and labor, and is productive of more efficient and uniform work, and that the use of the device of the invention prevents those injuries to the hands which are common in wire splicing operations when conducted with the hands and hand tools heretofore employed for this service.

Although I have shown and described herein a preferred embodiment of my invention, it is to be denitely understood that I do not desire to limit the application of the invention thereto and any change or changes may be made in materials, and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjoined claims.
